This is an old news report which has been beaten to death here in the forum about 6 months ago.
It was a real study but it was in a petri dish and not the human body.
I wrote some Indian doctors about it and they said they were not too impressed at this point of the research. They also said that one of the herbs is very similar to St. John's Wart and that this herb has strong anti-viral properties.
I prefer garlic. It is one of the strongest natural anti-biotics on the planet! :)
